DISTRIBUTION:

Hylesia peigleri (wingspan: males: 44-51mm; females: 53-69mm) flies in
western Mexico: Sonora: Yecora (6000ft); Sinaloa: Loberas (1975m).

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Larvae feed on Acacia drummondii (natural), Spiraea bumalda, Prunus virginiana, Prunus serotina and Prunus caroliniana.

This species probably broods continuously on a three month cycle. Flight records exist for March and August-September.

ECLOSION, SCENTING AND MATING:

Females extend a scent gland from the tip of the abdomen, and the night-flying males pickup and track the airbourne pheromone plume with their well-developed antennae.

EGGS, LARVAE, COCOONS AND PUPAE:

Eggs are deposited in clusters on hostplant foliage.

Hylesia peigleri larvae are highly gregarious and have the urticating spines typical of larvae from the Subfamily Hemileucinae.

Larval Food Plants

It is hoped that this alphabetical listing followed by the common name of the foodplant will prove useful. The list is not exhaustive. Experimenting with closely related foodplants is worthwhile.
